The adults of rice stem borer were counted after 30, 45 and 60 days after sowing (DAS) during rice growing season of 2002 and 2003. It was observed that after 30 DAS the adults preferred resting on crop, planted on 20th and 27th of June with variable number of seedlings hill-1. Similar trend was observed after 45 and 60 DAS. Number of white heads plant-1 was higher in crop planted on 27th of June and 4th of July indicating the relationship. It was further noted that seedlings per hill has no affect on adult resting preference and white heads as well. The maximum paddy yield was noted in crop planted on 20th of June and 11th of July.
